/*********************************************************************************************\
|
||||
This driver enables the display of the current time, numbers (both integers and floats) and
|
||||
basic text on the IoTTimer clock.
|
||||
|
||||
Template {"NAME":"IoTTimer Lo","GPIO":[32,33,0,34,3872,1312,0,0,10944,10912,640,480,608,4768],"FLAG":0,"BASE":18}
|
||||
|
||||
In addition, it is possible to set brightness (seven levels plus off) and clear the display.
|
||||
|
||||
To use, compile Tasmota with USE_DISPLAY, USE_DISPLAY_TM1640 and USE_IOTTIMER, or build the tasmota-display
|
||||
firmware.
|
||||
|
||||
Either use following template:
|
||||
Template {"NAME":"IoTTimer Lo","GPIO":[32,33,0,34,3872,1312,0,0,10944,10912,640,480,608,4768],"FLAG":0,"BASE":18}
|
||||
|
||||
or configure manually:
|
||||
For the IoTTimer clock assign the pins as follows from Tasmota's GUI:
|
||||
|
||||
GPIO12 --> "TM1640 DIN"
|
||||
GPIO13 --> "TM1640 CLK"
|
||||
|
||||
Once the GPIO configuration is saved and the ESP8266/ESP32 module restarts, set the Display
|
||||
Model to 13 and Display Mode to 0 using the command "Backlog DisplayModel 13 ; DisplayMode 0;"
|
||||
Before using it, set the Display Type to 1 (for IOTTIMER) using the "DisplayType 1" command.
|
||||
|
||||
After the ESP8266 restarts again, turn ON the display with the command "Power 1"
|
||||
|
||||
Now, the following "Display" commands can be used:
|
||||
|
||||
|
||||
DisplayClear
|
||||
|
||||
Clears the display, command: "DisplayClear"
|
||||
|
||||
|
||||
DisplayFloat num
|
||||
|
||||
Clears and then displays float (with decimal point) command e.g., "DisplayFloat 12.3"
|
||||
See function description below for more details.
|
||||
|
||||
|
||||
DisplayFloatNC num
|
||||
|
||||
Same as DisplayFloatNC
|
||||
|
||||
|
||||
DisplayClock 1|2|3|4
|
||||
|
||||
Displays a clock.
|
||||
Commands "DisplayClock 1" // 12 hr format
|
||||
"DisplayClock 2" // 24 hr format
|
||||
"DisplayClock 3" // 12-hour without seconds
|
||||
"DisplayClock 4" // 24-hour without seconds
|
||||
|
||||
|
||||
In addition, if you compile using USE_DISPLAY_MODES1TO5, setting DisplayMode to 1 shows the time,
|
||||
setting it to 2 shows the date and setting it to 3 alternates between time and date (using "DisplayRefresh [1..7]"
|
||||
for the time and seconds you want to show the time before displaying the date)

/*
|
||||
(specifically for its use in the IOTTIMER WiFi clock)
|
||||
|
||||
The WiFi LED clock called IOTTIMER has the following characteristics:
|
||||
- Controlled by an ESP-12F
|
||||
- Display with four 35 mm (1 12/32 in), two 21 mm (26/32 in), and three 12 mm (~1/2 in),
|
||||
seven-segment LED digits, plus special symbols (alarm, AM/PM)
|
||||
- TM1640B LED controller
|
||||
- R8010 RTC with CR1220 battery
|
||||
- Temperature sensor M1601
|
||||
- Ambient light sensor (analog voltage)
|
||||
- Buzzer
|
||||
- Three buttons on the backside
|
||||
- USB C port for power supply (only)
|
||||
|
||||
The TM1640B chip is a controller for a sixteen-digit seven-segment (plus dot) LED display.
|
||||
It is also sometimes used to control a 16 x 8 LED matrix. The controller is controlled
|
||||
through a proprietary two-wire serial interface bearing some similarities with I2C. The
|
||||
two wires are called CLK and DIN. We use two GPIO pins and one-microsecond sleeps to
|
||||
implement the required timing.
|
||||
|
||||
The wiring of the LEDs in the IOTTIMER clock has been optimized for a simple routing of the
|
||||
traces on the display board. The enumeration of the digit segments is non-standard, but
|
||||
consistent across all digits. The bigger digits have two LEDs per segment, controlled by
|
||||
separate digit lines of the LED controller. From the software perspective, they appear as
|
||||
two layers of four digits each.
|
||||
|
||||
The brightness of the LEDs can be controlled in seven steps (plus off). In theory, the
|
||||
brightness of the segments with two LEDs could be set in fifteen levels (plus off).
|
||||
To keep things simple and to avoid brightness gradients within segments, both LEDs of a
|
||||
segment will always be set to the same level.
|
||||
|
||||
The intention of this display driver (together with the drivers for the other components)
|
||||
is to be able to use the IOTTIMER as an alarm clock that can be fully integrated in your
|
||||
home automation using Tasmota and rules.
|
||||
|
||||
This driver is not a generic TM1640B driver as use cases of the TM1640B in different
|
||||
devices will differ significantly.
